Petr, 
I have been using an MFJ 1026 for a few years now, thanks to W5IZ. If used
correctly, it will perform as designed. The internal pre-amp for the noise
antenna is not very good, better not to use it and provide your own strong
pre-amp rather. If the noise antenna signal is strong, you do not need the
pre-amp on.
I have no knowledge about the other units, sorry.
I live on a small property, so the MFJ is used a lot due to the fact that
neighborhood noise can be high. It helped me making qsos with JA from my qth
and made my qso with VP6DX on 160m possible. If I had a large property with
Beverages or phased verticals, I might not have found it so useful. 
It is relatively cheap and can be very useful, another tool in your arsenal.
Use it to peak a signal or use it to cancel noise, as long as the noise
antenna is working and the amplitudes are correctly balanced, it will do as
told.

I have no connection with MFJ, normal disclaimer apply!
It may well be that the other units perform better, I cannot comment on
that.
